Comment 21 for bug 239722

I can confirm the bug on a SP6000 using Ubuntu 10.04.

The maximum resolution that it supports by default is 800x600. The odd thing is that even though I have enabled image stretching in the BIOS, the displayed screen is squarely at the centre of the monitor.

Anyway, by creating an xorg file trough a tty:

$ sudo service gdm stop
$ sudo Xorg -configure
$ sudo mv ~/xorg.conf.new /etc/X11/xorg.conf

and editing it to add the following HorizSync and VertRefresh settings in the Monitor section

Section "Monitor"
    Identifier "Monitor0"
    VendorName "Monitor Vendor"
    ModelName "Monitor Model"
    HorizSync 31-60
    VertRefresh 50-75
EndSection

along with adding 'modes "1024x768"' in the Screen's display subsections, it works fine.
